http://bugzilla.opensuse.org/show_bug.cgi?id=1073193 Bug ID: 1073193 Summary: No ttyS4 on Pine64 Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: aarch64 OS: openSUSE Factory Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: afaerber@suse.com Reporter: afaerber@suse.com QA Contact: qa-bugs@suse.de CC: agraf@suse.com, mbrugger@suse.com, pmladek@suse.com, stefan.bruens@rwth-aachen.de, yousaf.kaukab@suse.com Found By: --- Blocker: --- When enabling the uart4 node in the Pine64's Device Tree, there is no /dev/ttyS4 device available. No related error messages apart from deferred pinctrl probing. UART3 works fine as /dev/ttyS3. Workaround: none (use a different UART if you can) I am guessing that limiting us to four 8250 UARTs causes further UARTs to be silently ignored: CONFIG_SERIAL_8250_NR_UARTS=4 CONFIG_SERIAL_8250_RUNTIME_UARTS=4 We should probably revise those numbers. -- You are receiving this mail because: You are on the CC list for the bug.
